Application led October 15;, 1902. Serial No. 127,393. (Nomodel.)

To all whom it 11d/ay concer-n: v

Be it known that I, LOUIS KOsIOL, of Louisville, in the county of'J'efferson and State of Kentucky, have invented certain new and useful Improvements in Taste and Overl-low Fixtures; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, which form part of this speciication. fr .Y

This invention relates to waste and Vover- Iiow fixtures, and is an improvement upon the fixtures shown in my Patents No. 630,718 of August 8, 1899, and No. 647,297 of May 14, 1901. A

The invention consists in the novel and improved construction of lparts hereinafter.

claimed, and described with reference to the drawings, in which- A Figure 1 is a section view of the fixture as applied to a portion of a washbasin or other vessel, showing the valve open. Fig. 2 is a similar view showing the valve closed. Fig. 3 is an enlarged section of line 3 3, Fig. 1, looking upward, and'Fig. 4c is an enlarged perspective view of the plunger-valve.l

The sink or other vessel a to Vwhich it is desired to attach the improved fixture is provided with a screw-collar b, which may be integral therewith, if desired, into which is threaded the upper end of a cylinder c, forming the valve-chamber, said cylinder 'being closed at its lower end by a union d and nip-A ple e. The nipple e may be connected in the usual manner to the outlet-pipe f. Within4 the cylinder c is an annular plunger g, which;

is provided with an arch g', connectedto a stem g2, which extends upward axially .of the,v

cylinder c and is guided in central opening iu a perforated sieve-plate h, which is provided with a threaded lflange h', screwed into the collar b. is fast a disk z' of sufiicient area to cover,4 all the perforations in the plate N and provided on its underside with arubber Vgasket or packing-ring c, which, when the valve is completely lowered, will impinge upon the surface of plate h vand form an effectual water seal, preventing the escape of liquid from the vessel. The rod g2 is provided above the plate z' with a suitable pull, which On the upper end of this rod;

-rod lc, the upper end of which; is slidably confined in a bore in the lower portion of stem g2. Said stem g2 may be tubular, so as to permit the rod 7c' to play therein sufficiently to allow the valve k, to rise and fall Aand'close against or depend below the plun- "gel g' Onfthe upper end of the stem g is key g4, which is adapted to work through the slot N4 in plate h, and when raised above this slot 7o andthe stem partially rotated the key g4 will uphold the plunger. When' the` plunger is fullyjlowered, the upper end ofthis key comes below the plate h, and then by turning the stein the plunger can be locked in lowered po- 7 5 -sition. When the stenog2 isdrawn upward, so that water can escape'into the cylinder c from the vessela, the' cone-valve lc drops, as in Fig. 1, and permits the water to pass freely through the" openinginthe-plunger g, but upon press- 8o ing do'wn thevalve-stem g2 the valve 7c will first shut itself on the nipple e and then the plunger g will seat itself upon the valve k,

rInaking a tight and close iit, as indicated in Fig. 2, thus preventing escape of water and Valao the ingress of gases.

This construction enablcsthe device to be used as a plunger to vforce anyobstructions through the trap if the latterlrshould become choked, which would cause the cylinder c to fill with water. Then 9o by raising and forcibly depressing the plunger the valve @would close against the plunger andthefurther descent thereof would force Vthe water below it o'ut'of the cylinder into the pipe, v and thus an obstruction Y in the pipe could be forced ahead and removed.

Then the device is to Hbe used on overflow fixtures, the stem g may be short, so that when the plate c' is seated upon the strainer h, thus preventing the escape of water from Ioo the vessel, there will still be a free waterway below. On ordinary fixtures, however, the

plunger and valve will act as a gas seal. While the stein gl is shown as tubular throughout, this is not essential, as it may be solid, suitable provision bein g made for teleseoping the stein k".

The collar I) may be dispensed with if the outlet of the vessel a is suitably threaded for engagement of the plate 7L and cylinder e, this, however, forming no part of the present invention. \Vhen the valve is fully lowered and the stem of is turned to the right, the key y abuts against a stop gf on the lower side of plate 1l (see Fig. 3) and locks the valve in its lowerinost position, as indicated in Fig. 2, so as to eliectively resist any back pressure of water or gas.

Having thus described in v invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

l. The combination of a cylinder, the plunger therein and a stein for operating said plunger, having a guide-key, a guide-plate at the upper end of the cylinder having a slot for the passage of said key, a disk on the stein above the plate and a gasket on the under side of the disk, substantially as described.

2. The combination of a cylinder, the perforated plate in the upper end thereof provided with a keyway, a stein passing through said plate and having a key adapted to en gage said keyway, a plunger on the lower end of said stein iitted within the cylinder, and a valve loosely suspended from said plunger, adapted to close the opening thereinfwith a disk attached to the upper end of the stem above the perforated plate and provided with a packing on its under side adapted to prevent the passage of water through said plate, substantially as described.

2l. The combination in a waste and overflow fixture, of the vessel, the cylinder attached thereto, a perforated plate provided with a keyway in the upper end of said cylinder, the stem depending through said plate provided with a locking-key, a plate on the upper end of said stein provided with a packing on its under side, an annular plunger connected to the lower end of said stein and fitted within the cylinder, and a conical valve loosely connected to said stein and adapted to close the opening in the plunger substantially as described.

ln testimony that l claim the foregoing as my own l alix 1ny signature in presence of two witnesses.
